1.序言本文叙述了数模转换器的构成和最近的技术动向。数模转换器目前已从微型组件化进到单芯片集成化。因此对于用户来说,只要能区分输入、输出端和电源端就足够了。这样用户可以集中精力来考虑前后的连接方式用哪种接口为好。但是象模数转换器所涉及的问题一样,对于数模转换器,其精度、速度等规格也是多种 1. Introduction This article describes the structure of digital-to-analog converters and recent technical trends. Digital-to-analog converters have now moved from miniaturization to single-chip integration. So for users, as long as the input, output and power supply side is sufficient. This allows the user to concentrate on the interface before and after considering which interface is better. However, like the problems involved in analog-to-digital converters, digital-analog converters also have many specifications such as accuracy and speed
